“…While the neat PVA exhibited a shoulder peak at 298 nm, composite films showed broadband between 200-450 nm. This is attributed to the extended π-conjugated system of the MWCNTs sidewalls [9,21]. All composites exhibited nearly similar band configuration and slope of chart lines.…”

“…Incorporation of reinforcements (MWCNTs, micro cellulose or both) caused strong transparency loss even though the reinforcement content was only 5 wt %. Most of the transparency loss is due to the presence of MWCNTs [9,21]. As it was observed in Figure 10a), the large amount of incident light was absorbed by the components of film and absorbance line started between values of 2.5-3.0.…”

“…The Raman peak initially located at 1095 cm -1 corresponding to the C-O stretching. The band at 1245 cm -1 (G band) corresponds to C=C, sp2-hybridized carbon, derived from the MWCNTs structure [21]. And also, -COOH structure appeared at near 3050 cm -1 (G' band).…”

“…As shown in Figure 4b), at 1370 cm -1 (D band), a strong band appeared in the Raman spectra of MWCNTs which stem from the sp3hybridized carbon or structural defects. Additionally, at : Surface total energy 1550 cm -1 (G band), a relatively weak band corresponded to vibration of sp2-hybridized graphitic domains [4,21].…”

The purpose of this work was the fabrication of a conductive carbon nanotube (CNT) ink. The proposed CNT ink remained remarkably stable over several months. The method includes combining the covalent and non-covalent functionalization, resulting in ink that exhibits excellent storage stability. The covalent functionalization was performed in the acid medium using H2SO4 and HNO3, while the non-covalent functionalization used sodium dodecyl sulfate (SDS) and ultrasonication. The materials were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). FTIR and SEM confirmed that at the non-covalent functionalization, SDS was successfully adsorbed on the f-CNT surface, while at the covalent functionalization, the functional groups (-COOH, C=O and -OH) were inserted into the CNT surface. Voltammetry and EIS indicated that SDS in the presence of functional groups facilitates electron transfer by improved electrical conductivity. The final product was a well-dispersed CNT ink with an average ohmic resistance of 18.62 kΩ. This indicates that CNT ink can be used in the fabrication of electrochemical sensors.

In vivo imaging, which enables us to peer deeply within living subjects, is producing tremendous opportunities both for clinical diagnostics and as a research tool. Contrast material is often required to clearly visualize the functional architecture of physiological structures. Recent advances in nanomaterials are becoming pivotal to generate the high-resolution, high-contrast images needed for accurate, precision diagnostics. Nanomaterials are playing major roles in imaging by delivering large imaging payloads, yielding improved sensitivity, multiplexing capacity, and modularity of design. Indeed, for several imaging modalities, nanomaterials are now not simply ancillary contrast entities, but are instead the original and sole source of image signal that make possible the modality's existence. We address the physicochemical makeup/design of nanomaterials through the lens of the physical properties that produce contrast signal for the cognate imaging modality-we stratify nanomaterials on the basis of their (i) magnetic, (ii) optical, (iii) acoustic, and/or (iv) nuclear properties. We evaluate them for their ability to provide relevant information under preclinical and clinical circumstances, their in vivo safety profiles (which are being incorporated into their chemical design), their modularity in being fused to create multimodal nanomaterials (spanning multiple different physical imaging modalities and therapeutic/theranostic capabilities), their key properties, and critically their likelihood to be clinically translated.
